Description

Technical Field

[0001] This utility model relates to the technical field of ethylene glycol processing equipment, specifically an ethylene glycol drying processing equipment. Background Technology

[0002] Ethylene glycol (EG) is an important industrial raw material with wide applications in antifreeze preparation, polyester fiber synthesis, and electronic-grade solvents.

[0003] In these applications, the water content of ethylene glycol directly affects product performance: for example, it can lead to increased side reactions in polyester production and may introduce problems such as excessive conductivity in the electronics industry; therefore, industrial applications require deep drying of ethylene glycol to control its water content to below 100 ppm.

[0004] However, after drying, the processing equipment needs to dehydrate the processed material to remove internal moisture. Currently, dehydration methods include replacement or hot air drying. However, replacement requires frequent manual intervention and each replacement takes a long time. Hot air drying cannot quickly remove water from the inside of the material, resulting in low heat transfer efficiency and insufficient removal rate of moisture adsorbed inside the porous dried material.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example: This utility model provides a technical solution for an ethylene glycol drying equipment, such as... Figures 1-3As shown, the system includes: a base 200, on which an outer shell 100 is fixedly mounted; an installation cover 300 is fixedly mounted on the base 200 below the outer shell 100; a drying unit 600 is assembled inside the installation cover 300; a packing bed 500 is placed inside the outer shell 100, and the packing bed 500 is filled with molecular sieves 700; a turning unit 400 is rotatably mounted inside the packing bed 500, and the turning unit 400 is connected to the drying unit 600; a switching unit 800 extending into the turning unit 400 is fixedly mounted on the top of the base 200; the outer shell 100 is the external housing of the equipment, enabling the internal components to be assembled and operated internally, and the drying unit 600 connects with the cutting unit 600. The coordinated operation of the exchange units 800 enables the equipment to dehydrate and dry the internal materials without removing them. The drying points are distributed within the material layer, achieving dehydration and drying from the inside out, resulting in a more significant and faster effect. The packing bed 500 and drying unit 600 enable the equipment to selectively adsorb water molecules using internal molecular sieves. The turning unit 400 can turn the molecular sieves 700 after processing, allowing for adjustments to their position within the packing bed 500. This prevents the contact surfaces between the molecular sieves from remaining unchanged for extended periods, which could affect subsequent processing. Periodic turning ensures the absorption effect of the molecular sieves, and the friction during turning reduces impurity adhesion.

[0035] The material turning unit 400 includes a hollow rod 402 and turning blades 403. The hollow rod 402 is rotatably installed at the bottom of the packing bed 500, and the bottom end of the hollow rod 402 extends out of the outer shell 100. Four sets of turning blades 403 are fixedly installed on the hollow rod 402. Air holes 405 are provided on the hollow rod 402 between the turning blades 403. The hollow rod 402 can meet the arrangement and operation requirements of its own turning blades 403, and also meet the installation connection between the hollow rod 402 and the external air pipe. When external gas enters the hollow rod 402, it can be discharged through the air holes 405.

[0036] The drying unit 600 includes a fan 601 and a heating cylinder 603. The fan 601 is fixedly installed inside the mounting cover 300, and the output end of the fan 601 is equipped with the heating cylinder 603. The fan 601 is connected to the hollow rod 402 through the heating cylinder 603. The fan 601 can send in gas and heat the gas through the heating cylinder 603. The hot gas can then enter the hollow rod 402 to complete the drying operation of the molecular sieve.

[0037] The switching unit 800 includes an electric cylinder 801, a push rod 802, and a sealing sleeve 803. The electric cylinder 801 is fixedly installed on the top of the base 200. The push rod 802, extending into the space 402, is connected to the top of the electric cylinder 801. A sealing sleeve 803 for sealing the air hole 405 is fixedly installed on the push rod 802. The electric cylinder 801 pushes the push rod 802 to extend or retract, causing the sealing sleeve 803 on the push rod 802 to enter or exit the working state. When it enters, the sealing sleeve 803 seals the air hole 405; when it exits, the air hole 405 communicates with the hollow rod 402.

[0038] In one embodiment, a feed inlet 102 is fixedly installed on the top of the outer casing 100, a drain outlet 101 is fixedly installed on the bottom of one side of the outer casing 100, and a discharge outlet 103 connected to the packing bed 500 is fixedly installed on the bottom of the outer casing 100, with a sealing cap fixedly attached to the bottom end of the discharge outlet 103. The feed inlet 102 facilitates the injection of ethylene glycol, the drain outlet 101 discharges the processed ethylene glycol, and the discharge outlet 103 discharges the molecular sieves that have reached the end of their service life, facilitating replacement.

[0039] In one embodiment, the material-turning unit 400 further includes a motor 401 and a rotary joint 404. The bottom of the hollow rod 402 is fitted with a rotary joint 404 that is rotatably connected to the outer casing 100. The hollow rod 402 is also connected to the drying unit 600 via the rotary joint 404. The motor 401 is fixedly mounted on the top of the outer casing 100, and the output end of the motor 401 is connected to the hollow rod 402. The motor 401 drives the hollow rod 402 to rotate, causing the blades on the hollow rod 402 to rotate and turn the material. The rotary joint 404 serves as a connector, achieving both a rotatable connection between the hollow rod 402 and the outer casing 100, and ensuring connection with the external air pipe during rotation, thus preventing interference between the two.

[0040] In one embodiment, the drying unit 600 further includes a first air pipe 602 and a second air pipe 604. The output end of the fan 601 is connected to the first air pipe 602, and the fan 601 is connected to the heating cylinder 603 via the first air pipe 602. The other end of the heating cylinder 603 is connected to the second air pipe 604, and the heating cylinder 603 is connected to the hollow rod 402 via the second air pipe 604. The first air pipe 602 and the second air pipe 604 enable the heating cylinder 603 to be connected to the fan 601 and the bottom of the hollow rod 402, ensuring that the heated gas can smoothly enter the hollow rod 402.

[0041] In one embodiment, a fixing bracket is fixedly installed on the push rod 802. The push rod 802 is connected to the sealing sleeve 803 via the fixing bracket. Sealing rings are fitted on both the top and bottom of the sealing sleeve 803. The fixing bracket is a connecting component, fitted onto the push rod 802, and fixedly connected to the inner wall of the sealing sleeve 803 via three sets of brackets. The sealing sleeve 803 fits snugly against the inner wall of the hollow rod 402, and the external sealing rings enhance the sealing effect between itself and the interior of the hollow rod 402, preventing ethylene glycol from entering the interior during equipment operation.

[0042] As one embodiment, a support frame is fitted onto the heating cylinder 603, and the heating cylinder 603 is fixed inside the mounting cover 300 by the support frame. An electric heating wire for heating is installed inside the heating cylinder 603. When air enters the heating cylinder 603, the air can be heated by the electric heating wire; the electric heating wire is currently available, and its principle is the same as the heating principle in current hair dryers.

[0043] In specific implementation of this utility model:

[0044] S1. Ethylene glycol is injected into the packed bed 500 and sealed and allowed to stand. The molecular sieve 700 in the packed bed 500 absorbs the water in the ethylene glycol until the water content reaches the standard. Then the dehydrated ethylene glycol is discharged.

[0045] S2. Then, start the blower 601. The blower 601 can send in gas and heat the gas through the heating cylinder 603. The hot gas can then enter the hollow rod 402 to complete the drying operation of the molecular sieve until the water molecules inside the molecular sieve are removed. The hollow rod 402 dries the internal parts in sections through the air holes 405 on its own. It is worth noting that during the dehydration drying, the electric cylinder 801 needs to be started. The electric cylinder 801 pushes the push rod 802 to extend and retract, causing the sealing sleeve 803 on the push rod 802 to enter or exit the working state. When it enters, the sealing sleeve 803 seals the air hole 405. When it exits, the air hole 405 is connected to the hollow rod 402.

[0046] S3. During the dewatering process, the motor 401 is started, which drives the hollow rod 402 to rotate, causing the blades on the hollow rod 402 to rotate and turn the material. The rotary joint 404 is a connecting part to ensure that the two do not interfere with each other. It should be noted that the motor, fan and electric cylinder in this application are all existing and widely used in the field. The operating specifications can be determined according to the actual situation. In addition, the electrical components in this application are centrally controlled by an external PLC controller connected by wires.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
